No. Exif says -4EV exposure compensation was active (EXIF field 9204 "ExposureBiasValue"). But I invite you to google what can influence this value (except dialing it in).
Auto EV compensation (as I understand it -- and I can be wrong) actually is no compensation. The opposite, actually. It tries to maintain a correct EV exposure value by changing "the other parameter" if the predefined paramater (exposure time or aperture) has reached its limiting value.
Therefroe, with 1/4000s and -4EV, the camera had to ignore the f/5.6 setting and aim for something smaller.
The -4EV, in the first place, are most probably a simple user error...
EDIT...
I had a look at the EXIFs again. This image was the darkest in a bracketed exposure series. fs999 "forgot" to tell us about and I'm not amused... So, the -4EV wasn't dialed in but choosen by the bracket series. All else as I've said.
